Kidney and Parts of kidney

Each component of the human kidney has a different purpose in the filtration and excretion of waste materials from the body. The kidney’s primary components are as follows:

1. Renal Cortex:

The renal cortex is the outer layer of the kidney. The nephrons, or filtering units, within the renal cortex filter blood and create urine.

2. Renal Medulla:

Nestled well within the renal cortex, the renal medulla is the kidney’s internal part. Tubules in conical structures known as renal pyramids transport urine from the nephrons to the renal pelvis.

3. Renal Pelvis:

The kidney’s core contains the renal pelvis, a structure resembling a funnel. Pee is collected from the renal pyramids and directed into the ureter, which then transports the pee to the bladder, where it is stored.

4. Nephrons:

Nephrons are the kidney’s functioning units. Each kidney contains millions of nephrons, which consist of a renal tubule and a renal corpuscle. The renal tubule excretes waste items and reabsorbs valuable substances to form urine, while the renal corpuscle filters blood.

a. Renal Corpuscle:

The glomerulus and the Bowman’s capsule comprise the renal corpuscle. The glomerulus is a network of microscopic blood vessels known as capillaries that filters blood to produce a substance known as filtrate. The Bowman’s capsule collects the filtrate, enclosing the glomerulus.

b. Renal Tubule:

Attached to the Bowman’s capsule, the renal tubule is a lengthy, twisted tube. The distal convoluted tubule, loop of Henle, and proximal convoluted tubule are some of its segments. The renal tubule produces urine by altering the filtrate through reabsorption and secretion processes.

5. Renal Artery and Vein:

The kidney receives oxygenated blood via the renal artery, while the kidney expels deoxygenated blood through the renal vein. These blood channels are essential for the kidney’s absorption of nutrients and elimination of waste.

The primary kidney components in humans engage in waste filtering and excretion. Every component has a role in the kidney’s general operation, which includes keeping the body’s fluid balance and eliminating waste products from metabolism.
